Abstract: A blood aspiration assembly (20) comprises proximal (22), intermediate (50) and distal tubing (24), a reservoir (61) having an adjustable volume, an aspirator receiver (106) and a two-way valve (44). The reservoir (61) can be locked into selected withdrawal and discharge positions. The aspirator receiver (106) is connected between the distal and the intermediate tubing (24,50). The receiver (106) comprises a rigid casing (111) a resilient frusto conical plug (136) and a blood aspiration chamber (110) with a smooth liquid flow surface (116). The valve (44) and reservoir (61) can be operated to draw blood from the patient into the intermediate tube (50) to remove resident fluid from the aspiration chamber (110). A clamp or valve (154) can block intermediate tube (50) flow. The reservoir (61) has a predetermined fluid volume equal to that volume which, when withdrawn into the reservoir from the intermediate tube (50), results in the replace­ment of essentially all resident fluid in the aspira­tion chamber (110) and that portion of the apparatus distal to the aspiration chamber by essentially undiluted blood. A needle from a separate syringe is inserted through the plug (136) into the aspirator chamber (110) and a blood sample withdrawn. The tube clamp (154) can be opened and intra­venous fluid driven from the reservoir (61) back through the flow channels distal thereto, to force the resident blood back into the patient and fill the assembly with intravenous fluid.

Abstract: Aluminium suitcases or similar suitcases, which consist of several panels and a frame composed of profile elements, serve in many cases for transporting and for storing expensive equipment. In this case, the profile elements of the frame form two outer profiles and two central profiles. The outer profiles and central profiles are connected to each other by perpendicular profile strips. The intention of the invention is to improve the stability of a suitcase of this type. The invention proposes to manufacture the central profiles of uninterrupted and continuous profile strips, these central profiles having a rounded contour in the region of the suitcase edges, inserts being able to avoid weakening of the central profiles in the region of the suitcase edges. Furthermore, the stability can be increased by the fact that the individual profile elements are linked by means of pin connections to connection elements which connect the individual profile elements to one another. Finally, the outer profiles can advantageously be formed from angular profile strips, and the individual elements of the suitcase can be bonded together so that an extremely stable structure is achieved by this means too.

Abstract: The holding device for semiconductor slices (wafers) orients and secures the slice during transportation to the processing position but exposes the surface to be processed and secures the position of the wafer with the aid of a ring, which remains in the processing position, shortly before the processing position is reached. Under these conditions, the slice surface can be processed completely or with minimum shadowing and at the same time the transportation mechanism can be effectively protected from the processing, for example coating or etching. All the parts continuously exposed to the processing can easily be replaced. If the slice remains stuck in the processing station, it is pulled off by the positive-acting transportation safety device.

Abstract: A digital filter performs a predetermined arithmetic operation on input digital data inputted thereto in time-series manner by the predetermined first sampling period to thereby generate output digital data corresponding to a second sampling frequency which is N (where N denotes an integral number) times larger than the predetermined first sampling frequency. This digital filter provides a synchronizing signal generating circuit (20) and an operation control circuit (18). The synchronizing signal generating circuit detects the predetermined first sampling period of the input digital data to thereby generate a synchronizing signal having the second sampling frequency. The operation control circuit is activated by its internal clock which is asynchronous with the input digital data. This operation control circuit starts to perform its operation processes when the synchronizing signal is supplied thereto, thereafter it terminates the operation processes when a predetermined step number is completed.

Abstract: A system and apparatus for accurately delivering rubberized sheets from a supply, roll of stock material containing an intervening liner to an assembly station for subsequent assembling into an air spring or similar article of manufacture by eliminating the heretofore formation of a "free loop" therein. The supply roll and a liner take-up reel are rotatably mounted on a carriage transversely movable with respect to the longitudinal motion of the stock material. A hugger device has a plurality of timing belts which frictionally engage the liner at the take-up reel and winds the liner onto the reel at a constant linear speed regardless of the diameter of the reel and collected liner to move the rubberized sheet at a controlled rate toward the assembly station. The motion profile of the timing belts is controlled by a servo drive motor and the belts engage an arcuate portion of the circumference of the take-up reel to provide positive frictional drive engagement therewith. The carriage is moved along a pair of tracks by a ballscrew mechanism for bringing the cartridges of stock material and take-up reel into position with the timing belts and assembly station. An optical edge detection device and encoder, in conjunction with a motion controller, accurately control and regulate the system.

Abstract: A decoding apparatus decodes data, such as a digital video signal or the like transmitted from a coding (transmission) apparatus for coding an original datum with a less number of bits than that of the original datum. Adjacent sample data of a sample datum to be decoded are separated from the transmitted data. These data are compared with the sample datum to be decoded and the correcting datum is generated based on the compared output. The original datum is recovered from the sample datum to be decoded and the correcting datum, thereby the quantizing error or distortion can be reduced without increasing the encoding data amount.

Abstract: A travel speed limiting control system for lift trucks, par­ticularly of the "orderpicker" type, having an extendible mast (12,14,16) is disclosed. The truck travel speed which the operator can command is limited by factors including load weight, load elevation, heading angle and direction of truck travel (forward or reverse). Optionally, other factors may be involved, such as lateral tilt and load moment. An algorithm including the desired input factors is continually processed by an on-board micro­computer (10) to provide an instantaneous speed limit signal. In addition to its normal operating mode, the microcomputer is also arranged to operate in a "learn" mode, whereby it runs through the ranges of various input signals and develops a set of stored values which indicate the allowable ranges of the inputs, as well as offset or bias values which compensate for manufacturing tolerances occurring in the components of the system.
